Grand Bend is situated on the traditional territory of the Attawandaron and Ojibwe/Chippewa First Nations. It was ceded to the crown as part of a parcel called the Huron Tract, in Treaty 27, 1829. In the 1830s a group of English and Scottish settlers bought lots from the Canada Company, a land development firm. One of the original settlers, Benjamin Brewster gave his name to the village after he and his business partner David Smart secured rights to dam the Ausable River and started a sawmill in 1832. The villagers were mainly the families of the millhands and fisherman. Their homesteads were situated on the south side of the present village. For twenty years Brewster existed as an isolated lumbering community. Until the opening of the highway to Goderich in 1850, both people and provisions had to travel by water. Once road connections were complete, the village was no longer solely dependent on the forests for its livelihood and opportunities for new businesses emerged. Typical of many pioneer communities, the village assumed many different names throughout its history—Brewster's Mills, Websterville and Sommerville are all recorded. Early French Canadian settlers in the area referred to the present location of the village as "Aux Croches", 'at the bends'. Grand Bend survived as a name, perhaps because it was the most appropriate—the tight hairpin turn in the original Ausable River where mills were first established.
Improved roads and the arrival of the automobile near the turn of the century had the greatest influence on the growth of Grand Bend. Businesses were established to serve visitors and travellers along the highway, and with the beach, "The Bend" became a summer destination. In the 1940s, however, Grand Bend became the centre of a major controversy in the landmark court case of Noble v Alley. Wolf, a London, Ontario merchant, faced court challenges when he purchased property at Beach O'Pines in contravention of a restrictive covenant that prohibited the ownership of lots or cottages by persons of "Jewish, Hebrew, Semitic, Negro or coloured race or blood". The case was finally heard by the Supreme Court of Canada which ruled that the restrictive covenant as constituted was invalid.
''Gibbs v Grand Bend''
In the late 1980s, a landowner went to the Supreme Court of Ontario seeking a declaration that he was the successor in title to the entire north beach of Grand Bend, amounting to, by virtue of a land grant given to the Canada Company in 1836. Although successful at trial in 1989, it was overturned at the Ontario Court of Appeal in 1995, which held that, while the beach did not constitute lands reserved to the Crown, the owners had lost ownership to it over the years because of implied dedication and acceptance for public recreational use. As he was required to give the public access to the beach, he subsequently charged parking fees to the visitors and personally cleaned up the beach every night. In 1998 he reached agreement with the province and the village of Grand Bend to sell the property. There was a separate continuing ownership dispute relating to the harbour at the mouth of the Ausable River.
Present day
Grand Bend is home to a variety of stores and eateries. The main strip is the centre of activity in the town, with shopping during the day and night life venues during the evening drawing crowds. The atmosphere of Grand Bend has given the town a reputation of being Florida north.
